-Pressurized Water Reactor Containment Purge and Pressure-Vacuum Relief {BF/-}* | On December 15, 1995, a review identified that the requirements of Technical Specification 4.9.9 were never fully proceduralized at Unit 2. | ||
A reactor operator was reviewing the Technical Specifications and identified a Unit 2 surveillance procedure that did not adequately address one of the tests required prior to core alterations. | Specifically, the surveillance procedure that has been used to implement Technical Specification 4.9.9 did not direct testing of the Containment Purge and Pressure-Vacuum Relief manual initiation function. Thus, with the exception of the current refueling outage, it is likely that the Unit 2 Containment Purge and Pressure-Vacuum Relief manual initiation function was never tested prior to or during core alterations.

Specifically, Technical Specification 4.9.9 states, Containment Purge and Vacuum Relief isolation system shall be demonstrated OPERABLE within 100 hours prior to the start of and at least once per 7 days during CORE ALTERATIONS by verifying that Containment Purge and Pressure-Vacuum Relief isolation occurs on manual initiation and on a high radiation test signal from each of the containment radiation monitoring instrumentation | This event is re~ortable in accordance with 10 CFR 73 (a) (2) (i) (B) I any condition prohibited by the plant's Technical Specifications NRC FORM 388 (4-95) | ||

On December 15, 1995, a review identified that the requirements of Technical Specification 4.9.9 were never fully proceduralized at Unit 2.
Specifically, the surveillance procedure that has been used to implement Technical Specification 4.9.9 did not direct testing of the Containment Purge and Pressure-Vacuum Relief manual initiation function. Thus, with the exception of the current refueling outage, it is likely that the Unit 2 Containment Purge and Pressure-Vacuum Relief manual initiation function was never tested prior to or during core alterations. The most recent period of non-compliance was during the last core reload in late November through early December 1994. A similar issue of non-compliance did not exist at Unit 1. The cause of this occurrence was a lack of adequate controls for the development and revision of Technical Specification surveillance procedures. Corrective actions will verify the adequacy of Technical Specification surveillance procedures and will ensure that adequate controls are in place to maintain the adequacy of the procedures.

Prior to November 1994, it is l~kely that the same event occurred on each entry into core alterations and every seven days during core alterations since plant startup.
CONDITIONS PRIOR TO OCCURRENCE The plant would have been in Mode 6 or defueled prior to each' event.
There were no structures, components, or systems that were inoperable at the start of each event that contributed to the event.
DESCRIPTION OF OCCURRENCE On December 8, 1995, Unit 2 operators were making preparations for core alterations. A reactor operator was reviewing the Technical Specifications and identified a Unit 2 surveillance procedure that did not adequately address one of the tests required prior to core alterations. Specifically, Technical Specification 4.9.9 states, ~The Containment Purge and Pressure-Vacuum Relief isolation system shall be demonstrated OPERABLE within 100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> prior to the start of and at least once per 7 days during CORE ALTERATIONS by verifying that Containment Purge and Pressure-Vacuum Relief isolation occurs on manual initiation and on a high radiation test signal from each of the containment radiation monitoring instrumentation
- channels." The surveillance procedure that has been used to implement Technical Specification 4.9.9 did not direct testing of the Containment Purge and Pressure-Vacuum Relief manual initiation function. Additional testing was performed on December 8 that demonstrated the operability of the Unit 2 Containment Purge and Pressure-Vacuum Relief manual isolation function. Core alterations subsequently commenced with all required tests complete.

DESCRIPTION OF OCCURRENCE - (cont'd)
A Containment Purge and Pressure-Vacuum Relief surveillance procedure history review for both units was performed. It revealed that testing of the manual initiation function had never been proceduralized at Unit 2.
Thus, with the exception of the current refueling outage, the Unit 2 Containment Purge and Pressure-Vacuum Relief manual initiation function most likely was never tested prior to or during core alterations. This noncompliance issue wa_"s identified on December 15, 1995. The most recent period of non-compliance was during the previous refueling outage, which occurred in late November through early December, 1994. The Unit 1 procedure history review further revealed that only the most recent revision of the pre-core alterations Containment Purge and Pressure-Vacuum Relief surveillance procedures, Sl.IC-FT.RM-0014(Q)-~lrlla Containment or Vent Air Particulate Proc~ss Radiation Monitor" and Sl.IC-FT.RM-0016(Q)-
"lrl2a Containment or Vent Gas Effluent Process Radiation Monitor", did not contain manual initiation testing requirements. These particular procedure revisions were never used.
CAUSE OF OCCURRENCE The cause of this occurrence was that the program which implemented Technical Specification test requirements in the late l970's did not have adequate controls to ensure that all testing requirements were properly addressed. In addition, the current programs do not have sufficient controls to identify similar existing deficiencies, or to prevent removal of steps from-procedures which are required to comply with existing Technical Specifications.
PRIOR SIMILAR OCCURRENCES Though there have been six previous missed surveillances over the last six years, a review of LERs for Salem Units 1 & 2 identified one LER related to missed surveillances due to procedural deficiencies during the last two years. This is:
LER 272/94-008 ~Quarterly Channel Ftinctional Testing of Position Indication For Power Operated Relief Valves Missed On Both Units" identified an occurrence where a procedure was revised in response to Generic Letter 90-06 without a revision to Technical Specifications which resulted in missed surveillance testing of Power Operated Relief Valves while in modes 1 & 2.

SAFETY SIGNIFICANCE The safety significance for this incident is considered minimal since isolation bf the Containment Purge and Pressure-Vacuum Relief valves on a simulated high radiation signal is demonstrated as required by Technical Specification 4.9.9. The individual valves are routinely manipulated while in.Modes 5 and 6, which demonstrates proper manual circuit operation.
In adqition, Containment Purge and Pressure-Vacuum Relief isolation on the Phase A and Phase B manual isolation signals are also demonstrated to occur as required by Technical Specification 4.6.3.2.d on an 18 month frequen~y.
CORRECTIVE ACTIONS The immediate corrective action taken*was to verify the ability to manually close ~ach of the Containment Purge and Pressure-Vacuum Relief isolation valves from the Control Room.
The task specific procedure for Unit 2, Procedure S2.IC-FT.RM-0088(Q)-
"High Radiation Signal and Manual Initiation for Containment Isolation",
was revised to address the requirements of Technical Specification 4.9.9.
This procedure is now approved for use.
A task specific procedure for Unit 1 will be developed to address all the requirements of Technical Specification 4.9.9. This will be completed pribr to core alterations on Unit 1.-
A Technical Specification Surveillance Improvement Project (TSSIP) has been initiated for Salem station. As part of the TSSIP, a review will be performed to ensure that each Technical Specification surveillance requirement is adequately proceduralized. The review will be completed in two stages. The first stage will involve verification that each Technical Specification surveillance requirement has an associated procedure which is listed in the Technical Specifications matrix. These reviews will be prioritized such that Mode change requirements are verified prior to the applicable Mode change~ Administrative processes will also be. revised, as necessary, to ensure adequate controls are established for the revision of Technical Specification surveillance procedures. The first stage of the TSSIP will be complete prior to unit restart. The second stage of the TSSIP will, with exceptions, involve validation of the technical accuracy of the Technical Specification surveillance procedures. The exceptions will include inservice testing and inspection procedures, snubber inspection procedures and any procedures that will change significantly when Improved Technical Specifications are implemented. The second stage of the TSSIP is expected to be completed during 1997.
